Jim's TrueType QR Code Font
TL;DR
An experimental OpenType font was developed that converts bracketed text into QR Codes while keeping surrounding text legible. The font generation process involves creating glyph outlines and implementing complex features like Reed-Solomon error correction.
✦ Why It Matters
Engineers can use this QR Code font to enhance user engagement in documents and presentations by integrating scannable codes seamlessly.
Key Takeaways
- Explore the QR Font families for document integration.
- Utilize the build script for custom font generation.
- Implement Reed-Solomon error correction in data encoding.
- Maintain text readability while adding QR Codes.
Full Summary
Creating QR Codes that blend into text can enhance document interactivity. An experimental OpenType font was built to transform bracket-delimited text into QR Code symbols while maintaining the readability of surrounding text.
The font generation process utilizes a build script that produces glyph outlines and applies GSUB (Glyph Substitution) feature logic. Key components include a delimiter parser, byte expansion for data encoding, Reed-Solomon error correction for data integrity, and fixed mask rendering for QR module placement.
The printable ASCII glyphs are derived from the Liberation Sans Regular font, ensuring that non-QR text appears in a familiar style. The generated font families are named QR Font 1-L, QR Font 2-L, and QR Font 3-L, adhering to licensing requirements.
This innovation allows engineers and designers to incorporate QR Codes into their work without compromising text clarity.
